BUTTONHOLE-CUTTER.

Patented May 4, 1909.

Application filed May 29, 1908. Serial No. 435,647.

To all whom 'it may concer/a.'

Be it known that I, CARL ANDERSON, a citizen of the United States, residing at Austin, Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Buttonhole (utters, of which the follov. ing is a specification, reference being had to the accompanying draufings, forming a part thereof.

The purpose of this invention is to provide an improved device of the knife type for cutting button-holes.

It consists of the features of construction shown and described, as indicated in the claims.

vln the drawings Figurc 1 is a perspective View of the device embodying this invention. Fig. 2 is a plan view of the blade stripped of the accessory parts. F ig. 3 is a perspective viewr of the doublewinged gage removed from the blade. trating `the manner of assembling the gage and blade showing two successive stages of the process.

The blade, A, of thin steel has a straight edge, al, which is blunt, and a cutting edge, a2, oblique to the straight edge, the two edges meeting at a point for penetrating the fabric. The upper part of the blade is cut away for reducing it in n idth above the point at which the divergence of the edges, a* and a?, aifords the width necessary for the maximum size of button-hole for vwhich the tool is designed to be adapted. The blade is provided a ith a longitudinal slot, a, parallel to the blunt edge, al, said slot extending up beyond the shoulder, (L4, caused by the reduction of the width and throughout the greater portion of the length of the stem or narrower portion, A4, above that shoulder. This blade is provided with a double-winged gage,-that is, a gage which extends on Aboth sides of the blade. lt is made of a single piece of sheet metal, B, folded upon itself at the middle point of its length and having the two ends folded oppositely outward at right angles to the wings respectively to form the gage flanges, B1, B1, the device being cut away to reduce it in width at the fold to a neck, B2, of the width of the slot, a3.

The double-Winged gage and the blade are assembled together for engaging the neck, B2, in the slot, o3, by first entering one of the flanges, B1, through thc slot, and slightly springing the blade to the amount of its thickness only to permit one edge of thc slide to pass between the two wings, as seen in Fig. 4. The assembling is completed by sliding the blade between the two wings of the until the neck is in the slot, and then turning the two parts to bring their lateral edges parallel, the flanges, B1, being then at right angles to the straight edge, al, of the blade. At a little distance below the neck, both wings of the gage are apertured to receive a clamp screw, C, which takes through both said wings and the slot of the intervening blade, a clamp nut, D, boing provided at the opposite side for binding the parts together in adjusted position. The margin of the slot, a3, is graduated on one side of the blade for reading by the upper end of the wing of the gage upon that side, the graduations being made to correspond to the width of the tapered end of the blade at thc under surface of the gage llangesfthat is to say, the width of hole which the blade will cut upon being thrust through the fabric up to thc gage. In the drawings, the graduations are numbered from one to eight, cach unit of graduation corresponding to one-eighth of an inch of width of the exposed blade or width of hole which will be cut. For convenience in adapting the tool for measuring also the distance from button-hole to button-hole, the opposite surface of the blade from that having the button-hole width graduations above mentioned is graduated along the straight edge, a, in inches and fractions of an inch commencing from the upper end.

l claim :-w

1. A button-hole cutter comprising a tapering blade having a longitudinal slot, in combination with a double-winged gage made of one piece folded upon itself and reduced at the fold to form a neck of the width of the slot, and a clamp screw taking through both wings and the slot.

2. A button-hole cutter comprising a taparing blade having one edge blunt and the other sharp for cutting, and having a longi tudinal slot parallel to the blunt edge, in combination with a double-winged gage consisting of a single piece of metal folded upon itself and reduced at the fold to form a neck of the width of the slot and engaged therein,

the two Wings being oppostely hanged at the! my hand at Chicago, Illinois, this 15th day of ends at right angles to the length to forni May, 1908. stops upon opposite sides of the blade, and a clam screw taking through the Wings and 5 the s ot for clamping the parts in adjustable Vitnesses:
